What a call costs
Every plan includes every endpoint, so the only number that changes between plans is the price per call.
| Plan | Price | Calls per month | Per 1,000 calls |
|---|---|---|---|
| Sandbox | Free | 500 | $0.00 |
| Builder | $10/month | 10,000 | $1.00 |
| Launch | $30/month | 50,000 | $0.60 |
| Scale | $100/month | 300,000 | $0.33 |
What counts as a call
One request to any endpoint is one call, whether it returns a full natal chart or a single number. MCP tool calls count the same way against the same quota. There are no credits, tiers of endpoints, or per-feature surcharges.
